DAT Automatic Transformer Insulating oil Tan Delta & Resistivity Tester is high precision integrated testing instrument. Mainly used for measuring dielectric loss factor and the DC resistivity of oil liquid and insulating medium, the internal integration of the dielectric loss of oil cup, temperature control instrument, temperature sensor, dielectric loss test bridge, AC test power supply, standard capacitor, high resistance meter, high voltage DC source etc.. The instrument uses advanced measurement and control technology, complete automatic warming, temperature control, high-speed data sampling, operation, display, print and storage process. Advanced measurement principle and high digital technology make your work more relaxed and convenient.

The instrument adopts digital technology, intelligent automatic measurement, equipped with a large screen color touch screen, full Chinese menu, each step has Chinese tips, test results can be printed, the operator does not need to be skilled in the use of professional training.


1. High automation, heating, measuring dielectric loss, measuring resistivity can be completed once.

2. Three electrode type structure with an IEC standard, inter electrode spacing 2mm, can eliminate stray capacitance and leakage effect on the dielectric loss test results.

3. Instrument using medium frequency induction heating, PID temperature control algorithm. This heating mode has the advantages of non-contact, oil cup and heating body, uniform heating speed, convenient control, the temperature control in temperature within the preset range error.

4. Using advanced DSP and FFT technology to ensure data stability, accurate and reliable.

5. Internal standard capacitor for the SF6 charging three pole capacitor, dielectric loss and capacitance of the capacitor is not affected by ambient temperature, humidity, etc., so that the accuracy of the instrument after a long time to use is still guaranteed.

6. Large screen color touch screen, man-machine dialogue convenient, concise operation, clear.

7. With the lid off the high voltage, high voltage electrode cup short reminder, eliminate safety hazards, to ensure the normal operation of the safety of operating personnel and equipment.

8. With real-time clock, test date, time can be saved with the test results, display, print; equipment can display the ambient temperature, real-time detection of the test environment.

9. Automatic storage measurement data, can store 100 sets of measurement data.

10. Calibration function of empty electrode cup. The capacitance and dielectric loss factor of the empty electrode cup are measured to judge the cleaning and assembling condition of the empty electrode cup. The calibration data are saved automatically to facilitate the accurate calculation of relative capacitance and DC resistivity.
